"DWR" stands for "Durable Water Repellent," a special coating applied to fabrics to make them resistant to water. This coating allows water to bead up and roll off the fabric instead of being absorbed, keeping the wearer dry in rainy conditions. The combination of "🔍🌧️🌈" signifies the search for rainbows amidst rainfall, highlighting the beauty that can be found even in wet weather.
